Thanks, skeezix. I sometimes doubt the ability of my cheap setup. But every now and then, it really comes through and amazes me. (One of these days I'll be able to afford a better radio).
I have a local NAVTEX schedule. They generally broadcast the signal every four hours. I live in Seattle, WA and the nearest signal to me is located in Tofino, British Columbia, broadcasting on 518 kHz at 01, 05, 09, 13, 17, 2110 UTC.
Cheers.
